STRAP-EDGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 384,029,ldated June 5,1888. Application filed February 11, 1588. Serial No. 268,720.(Nomodel.)

To all whom it may concern.:

Be it known that I, J AMEsNELsoN FARLOW, of Lander, in the county ofFremont and Territory of Wyoming, have invented a new and Improved StrapEdging Machine, of which the following is a full, clear, and exactdescription. i

This invention has reference to a machine for beveling the edges ofleatherstraps; and

it consists in a machine for such a purpose constructed and arranged ashereinafter de- 4 scribed and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

AEgure 1 is a plan view of the machine. Fig. 2 is a side view, partly insection, of the machine. Fig. 3 is a transverse section on line z a inFig. 1. Fig. 4. is a similar section on the line y y of Fig. 1 withparts removed. Fig. 5 isa plan view of the front end of the machine witha portion removed, showing the cuttingknives in position for use; andFig. 6 is a detail view of one of the euttingknives.

In the construction ofthis machine 1 employ a frame-work havingcross-pieces 1 1, adapted to be secured to a bench or other foundation,and connected by means of longitudinal bars 2 2, on which is mounted across -piece, 3, adapted to slide on rods 4 4, and having anoperatingdiandle, 14,. by means of which it may be pulled back on therods 4. The upper part of the sliding cross piece 3 is provided with arecess, 6, in which rests a tilting presserbar, 7, loosely pivoted atits rear end by means of a slot, 8, connecting a U-shaped standard, 9.The rear end ofthe tilting presser-bar 7 is normally held in elevatedposition by means of a springarm, 10, secured at one end to the rearcross-piece 1, and having an upwardlyprojecting portion, 11, at theother end resting loosely in a groove, 12, in the lower part of thetilting presserbar 7, in which it is permitted to have alongitudinalmovement. The presser-bar 7 is provided with a suitableoperating-handle, 13, and is limited in its upward movement by thecross-pieee-of the LJ- shaped stop or handle lll. The forward end ofthetilting pressenloar 7 is formed with a projection, 15, which is adaptedto have a verters, 17, in reverse position, are fastened to the forwardcross-piece 1 and the sliding crosspieee 3, opposite to each other andadjacent to the other longitudinal bar 2.

It will be seen by the foregoing description that four cutters, 17 areprovided, located in pairs opposite each other, the cutters on thesliding crosspiece 3 being adapted to be brought toward the fixedcutters on the end"`L piece 1. The cutters 17 are peculiarly formed withflaring edges 20, so as to present double cutting-edges.

The sliding cross-piece 3 is held toward the front ofthe machine bymeans of coiled springs 21, mounted on the rods 4 and located betweenthe rear crosspieoe l and the sliding crosspiece 3. In operation thesliding crosspiece 3 is pushed back against the tension of the .springs21 and raises the tilting presser-bar 7 until a sufficient space isformed between the opposing knives 17 for the admission cfa strap, 22.The sliding cross-piece 3 is then permitted to come forward, and, byreason of the reaction of the springs 2l, presses the cross-piece 3firmly against the strap 22. The tilting presser-bar 7 is then forceddown against the movable knives 17 the springs 19 yielding to thepressure until the flaring cutting-edges 2() are brought against theupper corners of the strap 22. The same pressure also forces the lowercorners of the strap 22 against the flaring cutting-edges 20 of thefixed cutters 17. The strap 22 is then drawn across the machine betweenthe flaring cutting-edges 20, thereby beveling said edges. Thisoperation may be repeated until any number of leather straps have theiredges trimmed, as set forth. It will readily be seen that the' cuttersmay be removed at any time for sharpening.

Vhile I have described a specific construe tion of the parts of thismachine, I do not intend to limit myself thereto, as they `may be ICOvaried in form without departing from the spirit of my invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a strap-edging machine, the combination,with aframe having fixed and relativelymovable cutters and a sliding clamphaving ixed and relatively-movable cutters, or" a tilting presser bar orlever adapted to bear upon the movable cutters and force them intooperative position, substantially as described.

2. The combination, with the frame having a fixed cutter and avertically-yielding cutter, of a clamp movable toward and from these twocutters'and provided on its inner face with a fixed cutter and avertically-movable cutter, and a presser-bar movable vertically acrossthe strap-receiving space between the said knives and in line with thevertically-yielding knives, todepressthem intoengagementwiththestrapedges, substantially as sct forth.

3. A strap-edging machine consisting of a frame having a xed cross-piecewith a fixed cutter and vertically-movable spring-actuated cutter, and aspring-actuated sliding cross piece with a fixed cutter and averticallymovable spring actuated cutter, the sliding cross-pieceserving to hold a strap between the edges ofthe cutters, andaspring-actuated tilting presser lever or bar which is adapted to pressdown the movable cutters against the strap, substantially as described.

4. In a strap-edging machine, cross-pieces 1, connected by bars 4 androds 2, the sliding cross-piece 3, mounted on bars 4 and rods 2 andprovided with reacting springs 21, the tilting spring actuatedpresser-lever 7, with handle 13, and havingslots 8, engaging a standardand resting in recess 6 beneath handle 14 of cross-piece 3, and thefixed cutters 17 and movable cutters 17, mounted in casings 18 andresting on springs 19, said cutters being located ou the cross-piece 1and sliding cross-piece 3, substantially as described.

5. In a strap-edging machine, the combination,with clamp 3, mounted onbars 2 and having cutters 17, one of which rests in casing 18 uponspring 19, of cross-piece 1, having fixed cutter 17 and movable cutter17 in casing 18, resting on spring 19, and the presser-lever 7, withhandle 13, and resting in recess 6 of crosspiece 3 beneath handle 14,substantially as described.
